Can the government stop you from finding out it’s been looking through your private Facebook content as part of a “secret” investigation that’s not actually secret? That’s the question raised by an alarming case pending in the Washington D.C. Court of Appeals. Facebook has described the investigation as “known to the public,” and the timing and venue match the January 20th, 2017 Presidential Inauguration protests (known as “J20”), the investigation of which is indeed quite public. But even if the warrants pertain to another investigation, the government should not be allowed to impose gag orders with respect to any information that is already publicly known.
